If you have a need for a good fungicide that is totally organic for your lawn or garden then cornmeal could be just the thing for you. Recently researchers at Texas A&M University discovered that cornmeal attracts a member of the Trichoderma fungus family. This is a good fungus that will kill off disease causing fungi in a matter of weeks. The best part is it’s totally organic and safe so you and your family won’t be exposed to any dangerous chemicals. It’s also readily available and inexpensive. Since it is entirely organic, it can be used on edible crops as well.
